Say: 'I call only upon my Lord, and I do not associate with Him anyone. 20 Say: 'Surely I possess no power over you, either for hurt or for rectitude.' 21 Say, "No one can protect me from God, nor can I find any place of refuge but with him. 22 (It is) only a delivering (of communications) from Allah and His messages; and whoever disobeys Allah and His Apostle surely he shall have the fire of hell to abide therein for a long time. 23 Till (the day) when they shall behold that which they are promised (they may doubt); but then they will know (for certain) who is weaker in allies and less in multitude. 24 Say: 'I do not know whether that which you are promised is near, or whether my Lord will set for it a time. 25 He [alone] knows that which is beyond the reach of a created being's perception, and to none does He disclose aught of the mysteries of His Own unfathomable knowledge, 26 Except to a Messenger (from mankind) whom He has chosen (He informs him of unseen as much as He likes), and then He makes a band of watching guards (angels) to march before him and behind him. 27 That He may know that they have preached the message of their Lord. And He comprehendeth whatever is with them, and He keepeth count of everything numbered. 28
